MUD Quick-Change™ Options

features and applications

The wide range of available options enhance the
exceptional design versatility of the Master Unit Die
Concept. These options can also increase the cost
saving benefits and time saving features of this
superior approach to injection molding.
The basic design of MUD Quick-Change frames and
companion insert molds adds to these advantages.
The open configuration of the frame permits installa-
tion of water lines or hydraulic cylinders in the insert
mold. The smaller size and lighter weight of insert
molds simplifies machining. These design features
also simplify routine maintenance.

Frame options include interlocking ejector rails to lock
the insert mold’s ejector system to the master ejector
plate. The master ejector plate can be spring loaded
for returning the insert mold’s ejector system. It can
also be tied to the machine’s hydraulic knockout
system for stroking the insert mold’s ejector assembly.
